2006-up have no plug wires. The coil pack on each cylinder fires both plugs.

2003 -2005 had plug wires.

Gotta love it when they say crap like this. You should tell them if you let them replace it and that doesn't solve it then you're not paying. Any tree rat can swap parts to see if that's the issue.

Well, after I got it back and told them I'd do it myself, it's now super hard to start surges up and down in Park or Neutral, idles at 1100rpm in drive or reverse. Won't go more than 10mph and the gas pedal does absolutely nothing.

Just tried the new PCM from solopcms.com. Turned over, but wouldn't fire at all. Put old PCM back in and it fired up and ran (horribly). Here's a video of what it's doing. My dad's diesel is running in the background so disregard his engine noise.

Spent all weekend chasing down a cylinder 4 misfire on my dodge charger. Replaced coil packs, plugs, inspected wires, etc etc… all to no avail. It wasn’t until I went to the gas station this morning to fill up my gas tank. I’ve only had the car a week so I’ve not had more than a quarter tank of gas until today. After fling up, code went away and no misfire. Which means, it’s simply the #4 injector or fuel regulator. In any case, easy fix! So long story short, if any of you have a dodge charger and get codes po304 and p2311, it absolutely can be on the fuel side and not mechanical or electrical. Mine was! 👍
